Special events are handled at a very low level--as soon as they are
read. The read-event function processes these events itself, and
never returns them.
Events that are handled in this way do not echo, they are never grouped
into key sequences, and they never appear in the value of
last-command-event or (this-command-keys). They do not
discard a numeric argument, they cannot be unread with
unread-command-events, they may not appear in a keyboard macro,
and they are not recorded in a keyboard macro while you are defining
one.
These events do, however, appear in last-input-event immediately
after they are read, and this is the way for the event's definition to
find the actual event.
The events types iconify-frame, make-frame-visible and
delete-frame are normally handled in this way. The keymap which
defines how to handle special events--and which events are special--is
in the variable special-event-map (see section Active Keymaps).
